LeanCTX
Context intelligence layer that controls what AI coding agents can see and costs
Visit leanctx.com ↗What is LeanCTX?
LeanCTX is a context engineering layer designed for AI coding agents. It runs locally to manage what information reaches your AI model, applying access rules, filtering sensitive data, and compressing context to reduce token usage and costs. The system connects your sources, retrieves task-relevant information, and maintains source references for traceability.
Built for developers using coding agents like Cursor, Claude Code, Copilot, and Windsurf, LeanCTX offers caching, command-specific compression, session memory, and real-time cost tracking. The GitHub repository indicates it was built with support for multiple AI coding tools.
